Before you buy
- Get the 17-character VIN from the seller and run it at nhtsa.gov/recalls. It shows which recalls are still unrepaired on that exact car.
- Verify brake-module recall completion and current park-outside instructions.
- Request completion records for seat-belt bracket and bolt recalls.
- Confirm tailgate and rear-wheel lock-up recall status and ask about powertrain symptoms.
- Open recalls are repaired free at any GMC dealer, whoever owns the car — an open recall is a to-do item, not a bill.
